This is clearly due to the naive parsing scripts/genksyms/parse.y does: type_specifier: simple_type_specifier | cvar_qualifier | TYPEOF_KEYW '(' decl_specifier_seq '*' ')' | TYPEOF_KEYW '(' decl_specifier_seq ')' ... >Would it be difficult to teach it how to parse it? For someone familiar with bison/yacc this would seem not very difficult a job, but as far as I'm concerned this is not something I would feel comfortable trying to fix. Of course one could go the simplistic route and just add the array case here, but imo this wouldn't be the right way to deal with it.
